Abstract (en)

There is provided an improved electrically conductive metal honeycomb body (10) having a plurality of corrugated thin metal strips (18), which may be heater strips, extending in electrical parallel between otherwise electrically isolated connector plates (12,14). The corrugated thin metal strips (18) each have a flat central section (40c,fig.8). A first group of said strips are gathered at their flat middle portions and bent around one of a pair of rigid central posts (15,16), and second group of said strips are gathered and bent in the opposite direction about the other of said posts (15,16). Insulation means (20,22) in the form of a flexible woven ceramic fiber strip isolate the first and second groups from each other and from the central posts (15,16). The connector plates (12,14) define a segmented retainer shell about the body (10). A battery (156) is connected to the connector plates (12,14) whereby current flows from one connector plate through corrugated thin metal strips (18) to the other connector plate and back to the battery (156). <IMAGE>
